Checking bcc field in sent messages

Hi all,

Is there a way to see what recipients I had entered in the bcc header for a message in my +outbox (filed there by
Fcc: +outbox)? If not, what would I need to do in order to save this information in the future?

Thanks for any help!

/Henrik

If your MTA logs outgoing message recipients, you can look
there, otherwise I don’t think so.

Appeal to the authors of nmh? This seems to me to be a
misfeature of nmh. Surely, Bcc and Dcc should hide the recipient
list from the recipients, but it should not hide them from the
Fcc copy.

Yes, I believe Jon is spot on.

Yes, I believe Jon is spot on.

One disadvantage of including them in the filed copy is that if you forward or redist the message the Bcc and Dcc recipients will then be visible.  So any solution should involve options to other programs to insure this does have unintended side effects.

Thanks

I'd assume that the same mechanism used in comp would be used in redist,
and hopefully forw and repl and others as well. You are correct in that
the Bcc and Dcc fields must never be allowed to leak out, which leads me
to believe that they were not included in the Fcc copy in the first
place since protecting against leakage was too hard to implement.

OK, I understand. I'll make sure to save the addresses separately in the future. I guess I could also write a
small routine to harvest the bcc addresses before sending the message.

Thanks for the info and thanks for a great package!
